T
Triad-A triad contains three phosphor filled dots-one red, one green and one blue-arranged in a triangular fashion. Each of the three electron guns are dedicated to one of these colors (for example, the red gun excites only a triad’s red phosphor dot). As the guns scan the screen, each active triad produces a single color, which depends on the combination of excited color dots and how active each dot is.
U

Vertical Scanning-The movement the electron beam traces across vertical phosphor dots on the CRT.
